I got my phone stolen in April on a night out and the next day phoned O2 to get my phone blocked. I used the Blackberry Protect App to lock and wipe the device after trying to locate it multiple times via GPS.
After accepting that it was gone, I bought a new blackberry. 6 months later (yesterday), out of curiosity I decided to add my old BB pin to my new BBM. To my surprise, immediately I received an accepted response from this PIN. I sent a few messages and found out that the person who is now using my BB pin lives in the same area as where it was stolen.

I phoned O2 to check the status of the use of my stolen BB, but was told that it had been inactive since the day it was blocked. Can BBM pins are recycled once the phone has been rendered inactive, or is there any possibility that this is indeed my stolen phone being used?
